What is loft insulation?
We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.
- Waste packaging removed
- Eaves kept clear, with ventilation trays where air could be blocked
- Area under the cold water tank left clear so it cannot freeze
Why book with us in Suffolk
No pressure selling
You get everything in writing and decide in your own time.
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
How much does loft insulation cost in Suffolk?
Installing insulation in a home is zero-rated for VAT until 31 March 2027 and 5% after that, under HMRC's rules for energy-saving materials (notice 708/6). The Energy Saving Trust puts a typical professionally installed loft at about £750 from bare joists, or £600 to top up from 120 mm.
Building regulations in England
In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.

Questions about loft insulation in Suffolk
Do you cover the whole of Suffolk?
Yes. We cover every town and village in Suffolk, including Ipswich, Lowestoft and Bury St Edmunds.
Which council covers my address in Suffolk?
Addresses in Suffolk come under Suffolk council. The council matters for building control questions and some funding schemes.
How long does it take to insulate a loft?
Most lofts in houses take a single day. A large bungalow loft, a loft that needs clearing first or one with awkward access can run into a second day.
How deep should loft insulation be?
The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target for your address on the quote.
